Prelude> :info toUpper
Variable not in scope: `toUpper'
To bring 'toUpper' into scope, I put "import Char" in my program (a very simple program named "Text1.hs"):
module Text1 where
import Char
f = Char.toUpper 'a'
After starting ghci from the operating system shell, I enter ":load <program name>" at the ghci prompt, then evaluate the function 'f':
[localhost:~/Documents/myHaskellProgs] richard% ghci
.
.
.
Loading package base ... linking ... done.
Loading package haskell98 ... linking ... done.
Prelude> :load Text1.hs
Compiling Text1 ( Text1.hs, interpreted )
Ok, modules loaded: Text1.
*Text1> f
'A'
*Text1>

Where do I find foldl' in GHC? It's mentioned on
http://www.haskell.org/ghc/docs/latest/html/base/Data.List.html but
importing List and using "-package data" don't seem to make it appear. I'm
using GHC 5.02.2. I must be making some simple mistake.
